The Dwyer Series 655 Wet/Wet Differential Pressure Transmitter converts a positive or a positive differential pressure measurement into a standard 4-20 mA output signal.
Designed for use as a wet/wet differential pressure transmitter, units can be used to measure gas or liquid pressures compatible with 316/316L stainless steel wetted parts.
With an accuracy of ±0.5% FS, the Series 655 Pressure Transmitter can measure 5.0 inches w.c.d (1.24 kPa), with working pressures up to a maximum 100 psi (6.89 Bar).
